Thanks for replying, No error message on screen, at first I thought might have been the winpcap, but I have reinstall that, download the latest URL SNOOPER2 and getting the same results. This is what happens, when you lunch from the short cut (icon) a window blew open and then disappear. apply alt +tab you can see a window, but it is empty and will not appear on screen, seems to be hidden some how from viewing or accessing. I have use this software for a very long time without any issue.

If you download the portable version and unpack it into a new directory and run it, same result?Have you installed the WinPCap driver that UrlSnooper needs? It comes with it, but maybe try downloading the latest one from the WinPCap websiet? https://www.winpcap..../install/default.htm

Hey thanks for all the info, I did try the npcap b4 and was the same, I have rooted everything from the system and done complete new installation, somehow I believe a dll file somewhere maybe being use by some other software is in the system, but I will do it all over again with 'ncap' only... will let you on result...

Got it work Finally, I did a manual reg search carefully remove & stop some software from there, install a fresh WinCap followed by the prv Version URLS2, and it worked... Thanks for all the help guys.. stay safe
